The Diameter base protocol is intended to provide an Authentication,
Authorization and Accounting (AAA) framework for applications such as
network access or IP mobility in both local and roaming situations.
This document specifies the message format, transport, error
reporting, accounting and security services used by all Diameter
applications. The Diameter base protocol as defined in this document
obsoletes RFC 3588 and must be supported by all new Diameter
Working Group Summary
The document spent almost four years in the WG, which is
unreasonably long time. This was not a result of large
controversy, but rather ensuring nothing important breaks
in backwards compatibility. At IETF-79 the WG decided to include
in this version of Diameter support for Diameter over SCTP and
asked for the document to be updated and brought up again to the
WG and IETF consensus before it is submitted to IESG evaluation.
Three IETF Last Calls where hold.
FreeDiameter (www.freediameter.net) implements a previous
version of the specification.
A number of vendors have indicated interest on implementing
the specification due it correcting several known flaws.
Jouni Korhonen is the Document Shepherd for this document.
Dan Romascanu was the first responsible Area Director.
Benoit Claise is the current responsible Area Director.
